Description
QA1’s rebuildable twin tube shocks offer the performance, consistency, and tunability racers demand.
Formerly known as 51 and 53 series shocks, the QA1 5Q Series is a large body steel shock available in both bearing mount and stock mount configurations. Choose from 7” and 9” bearing mount bodies or various stock mounted lengths depending on rules and applications. Shocks are also available with rebound adjustable piston rods to adjust valving at the track.
Small details add up to provide great overall performance:
- Black zinc coating ensures a very consistent finish, creating a tight seal every time
- Scalloped base loop increases clearances in tight areas like upper control arms and shock mounts
- Pistons made of high-quality raw aluminum minimize variations compared to anodized parts
- Valve the shock with bleed shims or drill out bleeds to maximize tunability
QA1 5Q shocks can be:
- Re-valved and rebuilt by racers in minutes using basic tools
- Easily disassembled and reassembled thanks to two-piece body design
- Quickly filled and bled with a gland that features relief cuts and a hyper screw port
- Sealed with an upgraded kit that minimizes leaks, especially in high-rebound applications
- Rebuilt easily due to a slip-fit compression tube design
- Identified easily via a laser-engraved, black-anodized closure nut displaying serial numbers and valving
QA1 steel body shocks can also be used in coil-over configurations with the appropriate kits (sold separately). Racers can rebuild and re-valve their own shocks using available tuning and rebuild kits.
